Maximum On Power Mode Energy Consumption Standby Must not exceed 1 watt in standby mode User Information Requirement Background: Energy Star 3.0+ 30% Definition Energy Star 3.0 Specifications (Effective Nov. 1, 2008) Area < 680 in 2 PMax = 0.200*A + 32 680 in 2 ≤ Area < 1045 in 2 ≤ Area PMax = 0.240*A + 27 Area ≥1045 in 2 PMax = 0.156*A + 151 Example Area=437.07 inches squared Energy Star 3.0 =.2*437.07+32=119 watts Energy Star 3.0+30%= 84 watts (30% reduction) Note: Testing is based on the international test procedure IEC 62087, tested at default setting. The test accounts for on supply voltage (115v), ambient temperature and humidity.

Background: NEEA Energy Star Televisions Tracking System The 2009 opt-in program provided retailers incentives for sales of Energy Star 3.0+ 30% televisions. Energy Solutions tracks the sales as well as other details. Model number Energy consumption Tier (Energy Star 3.0 Plus 30%, Energy Star 4.0, Energy Star 5.0) Zip Code of retail location Screen size The tracking system places the sales in seven buckets based on the screen size. Source: Energy Solutions. Feb 2010. NEEA Electronic Source Data for Sept.-Dec. 2009.

Baseline Period NEEA measures savings from market intervention. Savings come from the efficient option over the inefficient option. Non-qualifying Energy Consumption is the consumption of televisions with less than Energy Star 3.0+30% efficiency in Q1 2009. Comes from QDI Strategies and Energy Solutions Data source: NPD Group, Consumer Electronics Association, QDI Strategies’ tracking of the Business and Consumer Electronics program; and the Energy Star Products List. Background: Measuring Energy Savings Discussions with Retailers Incentivized Units Sold (Sept.-Dec.) Q1 2009Q2 2009Q3 2009Q4 2009 Energy Savings by Size Category= Non Qualifying Unit Energy Consumption Prior to the Program – Qualifying Unit Energy Consumption

Results: Savings Rates NEEA will apply these saving rates to its estimate of total Energy 3.0+ 30% television sales by size category in the region. The weighted average savings rate for the incentivized units is 114 kWh/television. This rate is highly dependent on the screen size. Note: The Energy 3.0+ 30% average energy consumption comes from 112,477 observations. The calculation measures savings from on power mode (5.2 hours/day for 365.25 days per year)

Future Work In 2010, we will be tracking the savings for Energy Star 4.0 and Energy Star 5.0. Using the same seven screen size categories.
